目前,我省皖南及江淮地区大豆生产还是以农家品种为主,其中多数生育期偏长,影响后茬油菜或大(小)麦的及时播种,而且对病毒病、锈病等抗性差,植株高大容易倒伏,直接影响产量和质量的提高。为此,从1974年开始,我所着手适宜我省南方种植的早熟、高产、抗病、籽粒品质优良的大豆品种选育工作。一、选育过程 1975年—1976年我们对皖南大豆地方品种进行整理鉴定。1976年在区行鉴定圃中,发现青阳早黄豆(此行长5米,计有30株)有三株具五复叶类型的单株。秋收时
At present, the production of soybean in southern Anhui and the Yangtze River-Huaihe region is dominated by farmer breeds, most of which have a long growing period, which affects timely sowing of rapeseed or large (small) wheat and poor resistance to virus disease and rust and high plant height Easy to lodging, directly affect the yield and quality improvement. To this end, from 1974 onwards, I have embarked on a suitable early planting, high yield, disease resistance, good grain quality soybean varieties breeding in southern province. First, the breeding process 1975-1976 We Southern Anhui Province to sort and identify local varieties of soybeans identification. In 1976, in the district identification garden, it was found that there were three plants with five-leaf type in Qingyang early soybeans (5 meters in length and 30 in total). Autumn harvest time
